Description

FIELD

The subject matter herein generally relates to liquid cooling structures for cooling servers.

BACKGROUND

Liquid cooling is an effective cooling method for heating elements in a server. For example, one quickseal joint is set on a server body of the server, and other quickseal joint is set on a cabinet body. The one quickseal joint is connected with the other quickseal joint. The liquid can be input into the cabinet body to cool the heating elements in the server via the two quickseal joints. The quickseal joint has a built-in spring, and the two joints are lockable by the spring. The elastic force of the spring needs to be overcome when the two joints are brought together, and coupling the two quickseal joints is laborious.

As show in FIG. 1 and FIG. 2 , an embodiment provides a server 200. The server 200 includes a liquid cooling cabinet 201 and a server body 203. The liquid cooling cabinet 201 includes a cabinet body 2011 and a liquid cooling structure 100. The server body 203 is detachably installed in the cabinet body 2011. The liquid cooling structure 100 is used to cool the heat-generating elements in the server body 203.

As shown in FIG. 3 and FIG. 4 , the liquid cooling structure 100 includes a first support 10, a first joint 20, a second support 30, a second joint 40, a first magnet 50, and a second magnet 60. The first support 10 is set on the cabinet body 2011. The second support 30 is set on the server body 203. The first joint 20 is arranged on the first support 10. The second joint 40 is arranged on the second support 30. The second joint 40 is to match with the first joint 20. The first magnet 50 is arranged on the first support 10, and located at one side of the first joint 20. The second magnet 60 is arranged on the second support 30, and located on one side of the second joint 40. The first magnet 50 is aligned with the second magnet 60, and the first magnet 50 is a polar opposite of the second magnet 60.

When the first joint 20 and the second joint 40 are plugged together, the first magnet 50 and the second magnet 60 attract each other to provide attraction between the first joint 20 and the second joint 40, which reduces the external force for the insertion and saves labor for installing the liquid cooling structure 100.

In an embodiment, the number of the server body 203 and that of the liquid cooling structure 100 are multiple and equal. The server bodies 203 are detachably installed in the cabinet body 2011. Each liquid cooling structure 100 cools the heat-generating elements of one server body 203.

In an embodiment, the first joint 20 is the male joint of the quickseal joint, and the second joint 40 is the female joint of the quickseal joint. When the male joint is inserted into the female joint, the female joint provides elastic force to lock with the male joint, and the elastic force is opposite to the force for insertion. When the first joint 20 and the second joint 40 are brought together, the external force for insertion as in prior art needs to overcome the elastic force. In this embodiment, part of the elastic force which represents a resistance is offset if not overcome by the attractive force between the first magnet 50 and the second magnet 60, providing power for the insertion and reducing the external force used for the insertion.

In another embodiment, the first joint 20 is a female joint of the quick joint, and the second joint 40 is a male joint of a quick joint.

As shown in FIG. 5 and FIG. 6 , there are two first joints 20 and two second joints 40. In an embodiment, two first joints 20 are arranged on the first support 10, and two second joints 40 are arranged on the second support 30.

One of the first joints 20 and one of the second joints 40 are coupled for the input of cooling liquid, and the other first joint 20 and the other second joint 40 are coupled for the output of the liquid after cooling the heating elements. In an embodiment, the liquid is water. In other embodiments, the liquid may be other cooling liquid.

In other embodiments, one first joint 20 and one second joint 40 are arranged on the first support 10, and another first joint 20 and another second joint 40 are arranged on the second support 30.

There are two first magnet 50s. The two first magnets 50 are located outside the two first joints 20. There are two second magnets 60. The two second magnets 60 are located outside the two second joints 40.

In other embodiments, the number of the first and

second magnets

50 and 60 may be one or more than two.

In other embodiments, the first magnet 50 and the second magnet 60 may be located at other positions of the first joint 20 and the second joint 40. For example, the first magnet 50 can be arranged between the two first joints 20.

In an embodiment, the first magnet 50 and the second magnet 60 are structures which are magnetic. The first magnet 50 and the second magnet 60 are simple in structure, low in cost, and easy to install. The first magnet 50 and the second magnet 60 are connected to the first support 10 or the second support 30 by bonding or by fasteners such as rivets.

In other embodiments, one of the first and

second magnets

50 and 60 is a permanent magnet, and the other is a magnetizable metal structure.

The first magnet 50 has the same shape as the second magnet 60. Along the direction of the first joint 20 inserted into the second joint 40, the projections of the first magnet 50 and the second magnet 60 are coincident. The magnetic attraction force between the first magnet 50 and the second magnet 60 is evenly distributed, and the direction of the magnetic attraction force is parallel to the direction of insertion, so as to aid in aligning the first joint 20 and the second joint 40 for coupling.

In another embodiment, the shape of the first magnet 50 and that of the second magnet 60 may be different. The first joint 20 and the second joint 40 are aligned by the guide structure. For example, as shown in FIG. 5 , the first support 10 is provided with a guide part 11, and a hole 31 is defined in the second support 30. The guide part 11 may be inserted into the hole 31 and can slide in the hole 31. The guide part 11 and the hole 31 constitute a guide structure for the first joint 20 and the second joint 40 to be coupled.

In another embodiment, a hole 31 can be defined in the first support 10, and a guide part 11 can be set on the second support 30.

The number of guide part 11 and the hole 31 is one of each. The guide part 11 is located between the two first joints 20, and the hole 31 is located between the two second joints 40.

The guide part 11 is inserted into the hole 11, and the first joint 20 is aligned with the second joint 40 under the mutual attraction of the first magnet 50 and the second magnet 60.

When the first magnet 50 and the second magnet 60 are omitted, the first support 10 and the second support 30 can rotate relative to each other so that the first joint 20 and the second joint 40 can be aligned.

In other embodiment, the number of guide parts 11 and holes 31 can be two. Each guide part 11 is inserted and matches with a hole 31, and the first joint 20 and the second joint 40 can be aligned without the attraction of the first magnet 50 and the second magnet 60.

As shown in FIG. 5 , when the first joint 20 and the second joint 40 are coupled, a distance is defined between the first magnet 50 and the second magnet 60 along the direction of insertion. The first magnet 50 and the second magnet 60 are not touching. The magnetic attraction force when the first magnet 50 and the second magnet 60 are separated is smaller than the magnetic attraction force when the first magnet 50 and the second magnet 60 are together. When the first joint 20 and the second joint 40 are disconnected, the direction of the magnetic attraction force is opposite to the separation direction, but the magnetic attraction force will become smaller as the distance between the first magnet 50 and the second magnet 60 becomes larger, and the first joint 20 and the second joint 40 are in the opposite direction. The elastic force between the first joint 20 and the second joint 40 will still provide power to release the first magnet 50 and the second magnet 60 against any magnetic force, so as to reduce the external force required to release or reduce the attraction between the first magnet 50 and the second magnet 60.

The overlapping area of the projection of the first magnet 50 along the insertion direction and the projection of the second magnet 60 along the insertion direction is greater than a predetermined value, so that the magnetic attraction force between the first magnet 50 and the second magnet 60 is evenly distributed, and most of the external force for coupling is offset, and the first magnet 50 and the second magnet 60 move stably along the insertion direction.

For example, when the liquid cooling structure 100 does not have the first magnet 50 and the second magnet 60, the external force required for overcoming the elastic force measured by a push-pull force meter is 2 Kg. When the liquid cooling structure 100 includes the first magnet 50 and the second magnet 60, the required external force for coupling the first joint 20 and the second joint 40 measured by the push-pull force meter is 0.4 Kg, and the external force measured for separating the first joint 20 and the second joint 40 is 0.2 Kg. When the liquid cooling structure 100 includes the first magnet 50 and the second magnet 60, the external forces for coupling and for separating the first joint 20 and the second joint 40 are much less than those required when the first magnet 50 and the second magnet 60 are omitted.

In the cooling structure 100 and the server 200, the first magnet 50 and second magnet 60 with opposite magnetism attract each other to provide power for the coupling of the first joint 20 and the second joint 40, and reduce the external force required, so that the installation of the liquid cooling structure 100 is labor-saving.

The embodiments shown and described above are only examples. Even though numerous characteristics and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the detail, including in matters of shape, size and arrangement of the parts within the principles of the present disclosure, up to and including the full extent established by the broad general meaning of the terms used in the claims.
